[Dovecot] 1.1rc1: Maximum number of mail processes exceeded

[Jan van den Berg]

Before you start Dovecot type this in you shell:

ulimit -n 65000

I don't know how the use of the 'unlimited' word works: maybe this is
only 1024?

Cheers,

Jan

I'm getting "Maximum number of mail processes exceeded" messages when
512 imap Processes are active.

Dovecot reports:

Warning: fd limit 1024 is lower than what Dovecot can use under full
load (more than 1712). Either grow the limit or change
login_max_processes_count and max_mail_processes settings

But in my /var/service/dovecot/run script I use:

#!/bin/sh
mkdir /var/core
chmod 1777 /var/core
echo /var/core/%p > /proc/sys/kernel/core_pattern
ulimit -n unlimited
ulimit -c unlimited
/usr/local/sbin/dovecot -F

So how can I raise the filedescriptor limit above 1024
(linux-2.6.24.2, Debian)?
